will be so arranged as to remain in a si roughness of the water in which it is located.

Other objects of the invention and the feai lty will be apparent from the description taken in connection of which- Fig. 1 is a perspective view of a floating dock embodying my invention; i

Fig. 2 is an end elevation thereof with certain parts broken away; and

Fig. 3 is a detailed section of the connection between one of the supporting memfollowing bers and the platform and one o Vthe ponl toons. v

Referring to the drawings, 10 indicates a platform which is preferably wider at one end and the other end is of suliicientlength to serve as a landing platform vand other aircraft and also as aplatform from which airplanes may means that the platform must be several hundred feet long and preferably 150 feet or more in wi th at its narrow end. The narrow end 11 is supported on a pontoon 12, of suitable size, and the opposite end is supported on two pontoons 13 and 14.

It will be understood that theV drawings are more or less diagrammatic and are inerely illustrative of the principles of my invention without being accurate as to the proportions of the various parts of the structure.

k,Each of the pontoons is connected with the platform by a. series of struts and braces 15 to be securely attached thereto. The platform itself will be made with trusses and other structural elements of suitable size and strength to support the platform and the -load that it is intended to carry.

The pontoons may be used for lvarious purposes, in addition to supporting the plat- 10, For example, one of the 19011.`
